Abstract

Owing to the absence of dislocation defects and grain boundaries, the amorphous structure of metallic glass possesses superior mechanical properties compared to its crystalline counterparts. Koji Nakayama and co-workers present on p. 872 a method that is capable of producing metallic glass nanowires. The image shows that the free end wire in the center oscillates like a sine-wave pattern implying extremely high elasticity. The authors have succeeded to measure these mechanical properties at the nanoscale.
